What are robocalls or spam calls?

A robocall is short for "robotic call" and is defined as a phone call that uses a computerized autodialer. Once the call has been answered, the autodialer either plays a recorded message or connects the call to a live person. Some robocalls use personalized audio messages to simulate an actual personal phone call and may individually address the recipient by name.

Spam calls can be a nuisance and, in many cases, a threat. YouMail, a third-party robocall blocking software company, estimates that more than 50 billion robocalls were made in 2021.

What are the different types of spam calls or robocalls?

Types of spam calls or robocall scams include:

  • Spoofing calls
  • IRS scams
  • Charity scams
  • Travel scams
  • Customer care scams
  • Loan scams
  • etc.

Example 1: Hi, it's Mia. Important announcement, due to the recent COVID-19 coronavirus, the IRS is extending tax filing deadline and settling past-due tax debt. If you currently owe the IRS more than $10,000 in back owed taxes and need help press 1. If this is a call in error please press 7 to be removed. We can put a stop to wage garnishments, leans, and lower or eliminate the amount you owe.

Example 2: Hello this is an important message regarding your credit card payment. Due to the current epidemic of coronavirus, the cardmember services decided to eliminate your monthly payments and interest rates. Credit card members can now avail monthly payments elimination and lower interest rates. To speak to a representative please press 1.

Are Robocalls Illegal?

In the U.S, some robocalls are considered legitimate and are allowed without permission under the FTC’s rules. 

Here are some legit robocalls that are allowed and why.

  • Informational message robocalls are telling you that your flight has been canceled or reminding you about a medical appointment.
  • Debt collection robocalls are businesses that are legitimately trying to collect a debt and are allowed to use recorded messages to reach you. However, services that attempt to sell you services to reduce your debt are not and are probably scams.
  • Healthcare provider calls are from pharmacies reminding you to refill a prescription.
  • Messages from charities can make these calls themselves. But if a charity hires someone to make robocalls on its behalf, the robocalls can only go to prior donors or members of the charity. They must also include an automated option to let you stop future calls. 

How to identify and avoid spam calls/robocalls.

Here are some tips to identify and avoid spam or fraudulent callers.

  • Do not respond to calls or texts from unknown numbers or any others that appear suspicious.

  • Never share your personal or financial information via email, text messages, or over the phone.

  • Be cautious if you’re being pressured to share any information or make a payment immediately.

  • Scammers often spoof phone numbers to trick you into answering or responding.  Remember that government agencies will never call you to ask for personal information or money.

  • Always check on a charity (for example, by calling or looking at its actual website) before donating.

  • If the caller represents a generic sounding organization such as “HealthCentral 2020”, “Local Air Duct”, “The Government”, or not even bothering to identify their organization, then it is a scam. 

  • If there is pressure to act now, it is a scam.

  • Recorded generic calls from marketing agencies or unknown numbers are likely spam calls. 

  • If the caller claims to know you but does not know your name, it is a scam.

  • If the caller claims to represent a preexisting relationship and cannot cite an account number, or otherwise prove they are who they purport to be, it is a scam. 

  • A legitimate business calling one of their clients should already know everything they need about their client. Beyond perhaps verifying a birthdate, the customer should provide no information to the caller.  

  • If the caller wants money, cash cards, social security numbers, credit card or bank account numbers, shoe size when you are 14 years old, mother’s maiden name, etc, It’s a scam. Legitimate requests for payment can be done via mail.

What happens if you answer a spam call?

If you answer a spam call, it could lead to more spam calls. By picking up the phone you are essentially telling robocallers that your number is active and they could in turn sell your number to other telemarketers. It’s important not to answer calls from unknown numbers. If you do happen to answer such a call, hang up immediately.

Here are some steps to take if you answer a spam call.

  1. Hang up as soon as you realize it’s a robocall. The less you engage, the better. If you talk or react, the call may be marked as “live,” and you will be subject to more of them.
  2. Avoid saying the word “yes” if you can. Many robocalls scams start with a question like “Hello, can you hear me?” to which people may reply “yes” without thinking. They can then store the recording of your confirmation and use it for fraudulent activities. So, avoid saying yes where possible.
  3. Avoid following the bot’s instructions. Robocalls sometimes prompt you to take action, such as “press 1 to speak to a live representative'' or “press 2 to unsubscribe” and so on. By following instructions, you confirm to the robocallers that you are a potential victim and invite further robocalls. Try to avoid taking action.
  4. Report the call to the FTC. You can report robocalls to the Federal Trade Commission at By reporting the number which appears on your caller ID, you help the FTC track down the scammers behind the call. The FTC takes the phone numbers you report and releases them to the public each business day. This helps phone carriers and other partners that are working on call-blocking solutions. Reports also help law enforcement identify the people behind illegal calls. 
  5. Exercise caution. The damage that robocall scams can do is significant. Even if they don’t get your credit card information, they will waste your time. Proceed with caution every time you see an unknown caller ID. If a business is calling you, you can hand up, find their contact number on their website, and call them back to check if the call is legitimate.

We also recommend registering your phone numbers at DoNotCall.govAlthough this FTC registry won’t spare you from calls from scammers and thieves intent on breaking the law, it should prevent you from receiving “live” telemarketing calls, which are regulated by the federal government but are not illegal. You can also report fraud to the Federal Trade Commission.

What does Verizon offer to block spam calls on mobile phones?

For wireless customers, Verizon’s Call Filter can help you avoid unwanted calls. Call Filter blocks potentially fraudulent calls by automatically sending them to voicemail, but you can also block unwanted or nuisance calls with the free Call Filter app or through My Verizon. Upgrade to Call Filter Plus to identify unknown callers by name and customize your spam block list. For the home, Fios Digital Voice customers automatically get Spam Alerts for free, which warns of potential fraud calls, and can also opt in for Nomorobo through My Verizon, a free tool used to stop unwanted calls from ringing on your home phone.

The Call Filter app and My Verizon allow wireless customers to report a number as spam. This information will help us improve our spam detection service.

What is Verizon doing to prevent spam calls?

Robocallers are not going away anytime soon, but Verizon is committed to stopping robocalls so we offer free tools to our mobile and home customers.

  • For mobile, Verizon’s Call Filter is a free service that screens and autoblocks incoming spam calls based on risk level and the spam filter is set to automatically send potential fraud calls to voicemail.
  • For the home, Fios Digital Voice customers automatically get Spam Alerts for free, which warn of potential fraud calls, and can also opt in for Nomorobo through My Verizon, a free tool used to stop robocalls from ringing on your home phone.

While there may not be a silver bullet that entirely ends these activities, we're fully committed to fighting the scourge of robocalls. Verizon is a founding member of the US Telecom Industry Traceback Group, an industry-led organization that traces back suspicious robocall traffic, stops many illegal robocalls, and helps enforcement agencies catch the bad guys. Because most of the most egregious robocalls originate with service providers that look the other way and accept illegal traffic, Verizon has urged the FCC to establish a "chain of trust" between the originating provider and the carrier that terminates the call to the U S. consumer.

We are signing mobile calls using the industry’s STIR/SHAKEN standard, which helps verify that a call is in fact from the number displayed on the Caller ID and not spoofed. Our Fios Digital Voice customers will now have more confidence that the caller ID information they receive for a verified call is accurate.

Verizon automatically blocks in the network calls that we have determined are highly likely to be illegal based on reasonable analytics that incorporate caller ID authentication information. Verizon also uses STIR/SHAKEN technology to update our spam detection algorithm used by Call Filter, in real-time which may, in some cases, reduce the chances of incorrectly blocking or identifying a “good” call as “Potential Spam.” 

Through the efforts of Verizon and our partners, we are starting to curb the increase in robocalls.


How is Verizon protecting legitimate calls?

Verizon wants to ensure that its customers receive good and wanted calls. Customers can let us know if we incorrectly identify or block a wanted call as spam.  Calling parties can contact us if they believe their calls have been incorrectly blocked or labeled or that they have been adversely affected by information provided by the caller ID authentication framework.  Both customers and calling parties can contact us at our Spam Feedback website And because some robocalls are good, we educate legitimate businesses about “best practices” they can follow to reduce the risks that they get caught in blocking or labeling tools.
